Description
Technical field
The present invention relates to mix handover control apparatus and GSM and hand-over method in the GSM that the service of communication quality assurance type and different a plurality of services of non-assurance type service are provided.
Background technology
As transferring technology, there are the network leading type transfer (handover) and the mobile station leading type that in cellular systems such as PDC, IMT-2000, extensively adopt to transfer.
The basis that the network leading type is transferred is; Make the incoming level and the quality of reception of moving table measuring peripheral cell; To the relevant mode that can become the information of the candidate sub-district of switching the destination of network-reporting, auxiliary (assist) type of promptly so-called travelling carriage is transferred by control signal.
The network terminal that has received control signal is also added the information that the networking ends such as Radio Resource behaviour in service of candidate sub-district have, and the sub-district, destination is switched in decision.In addition, network terminal is switched the sub-district, destination and is transferred processing to the travelling carriage notice after the preparation indication is switched in the base station that covers switching sub-district, destination.This transfer generally is used for the sub-district switching that the communication channel of communication quality is kept in requirement.
This network leading type hand-over method is characterised in that mobile station in selecting is switched the candidate (candidate) of destination, but final switching destination is determined by network; Can move the sub-district switching of you and the transfer path switching of network terminal in same timing.Thus, can realize reliable and transfer at a high speed to optimal sub-district.
But the shortcoming of network leading type hand-over method is that controlled step is more, also has unnecessary state of a control such as signal wait state more.Especially, when travelling carriage can't normally hand over to the switching place sub-district of being indicated, it handled comparatively complicated.Whether capture the electric wave of transferring the destination no matter move you, network terminal is all carried out the path hand-off process of user data, and therefore, state is inconsistent when transferring failure, need carry out these are handled the processing of cancellation.
Here, just can reduce to transfer failed probability as long as carry out appropriate region (area) design.But what need to consider is, service area is outer waits unavoidably because edges of regions and tunnel etc. cause temporarily being in, so causes producing a certain proportion of transfer and fails.
On the other hand, the mobile station leading type is transferred, and to be travelling carriage independently determine to switch the sub-district, destination according to incoming level and the quality of reception of a plurality of peripheral cells, carries out the transfer mode of transfer at the arbitrary timing of travelling carriage.
The mobile station leading type in order to shorten the wireless synchronization time, can make up following controlled step in transferring, and switches the candidate of sub-district, destination and receives the relevant notice of switching the channel information of sub-district, destination from network terminal to the network terminal notice in advance.But, with the network leading type transfer different, network terminal need not switch the destination channel Radio Resource guarantee the controlled step such as setting with switching timing.
Sub-district switching and network leading type that the mobile station leading type is transferred under the communications status that is mainly used in common signal channel are transferred in the connecting moves again when failing.
The mobile station leading type is transferred and is characterised in that, travelling carriage independently carries out the sub-district and switches, and network terminal is carried out the change of transfer path after switch the sub-district, therefore can simplify control on the whole.Advantage is, when supposing that travelling carriage fails normally to capture the electric wave from the sub-district of initial decision, also can the action of network terminal do not exerted an influence, as long as begin the control of network terminal in any successful stage of sub-district retry.
But, owing to independently switch (switch), therefore can't consider the transfer of the information that the network terminal such as behaviour in service of Radio Resource have through travelling carriage.Especially, require certain communication quality keep with the sound of Radio Resource and TV telephone service in and be not suitable for.In addition, be to have carried out after finishing having confirmed through control signal to transfer because switch in the path of user data, so the instantaneous change of transmission delay is big.
